I walk up with these in hand
Irritool has:
small flat screwdrive
large flat screw driver
phillips head screw driver
hex key for PGP adjustments
hex key for toro adjustment
paperclip size "poker" for clearing nozzles
punch for making a hole for emitters

and the Knipex pliers

And for the cold weather guys, a quick trigger torch is a must for repairing cracked copper and brass

My auto mechanic was ranting and raving about his Knipex pliers last week and said that he couldn't understand how I could operate with just channel locks.

That line locater is pretty cool. Does it work on non-metallic objects?

You can run a "sonde" down a pipe to locate pipes that do not have conductors in them.
Also the device can locate live electric lines and radio frequency lines with out any transmitter needed.
Not worth a darn for locating solenoids though!
